At this point I've heard enough from both. It's not like we don't know who Trump is or what he's about, while Biden has been around for longer and is probably senile. Not that Trump seems all that sane by comparison either. Is there anything that Biden could really say that would make you vote for him, or Trump for me? It's less a debate and more, in my opinion, a showcase of a very low point in American politics in front of an international audience, and it's just not something I'd enjoy watching anymore.
I'm more interested in Biden's VP pick, as there's a very real chance that person may end up President if Biden wins.
